Title : Inflammation and the osteogenesis ability of mesenchymal stem cells the effect of natural compounds
Abstract:
Inflammation has a significant impact on the osteogenic differentiation and function of mesenchymal stem cells (MSCs). Proinflammatory cytokines like TNF-α, IL-1β, and IL-6 have been shown to inhibit osteoblast differentiation, induce apoptosis in osteoblasts, and impair their migration and function. This disrupts the delicate balance between bone-forming osteoblasts and bone-resorbing osteoclasts, leading to abnormal bone loss or formation. The mechanisms by which inflammation impairs osteogenesis involve complex signaling pathways. Inflammatory mediators can activate the NF-κB pathway, which in turn inhibits the osteogenic differentiation of MSCs. Inflammation also alters the expression of genes and transcription factors critical for osteoblast development. Interestingly, some natural compounds have demonstrated the ability to mitigate the negative effects of inflammation on MSC osteogenesis. For example, studies have shown that compounds like curcumin, resveratrol, and vitamin D can suppress inflammatory cytokines and promote osteoblast differentiation even in the presence of inflammatory stimuli. Our previous study investigates the impact of apigenin, a natural compound, on the osteogenic differentiation of human mesenchymal stem cells (hMSCs) by inhibiting inflammation through the modulation of the NF-κB/IκBalpha pathway. Apigenin was found to have stimulatory effects on osteogenic differentiation and anti-inflammatory properties. By targeting the NF-κB/IκBalpha pathway, apigenin neutralizes the inhibitory effects of inflammation on hMSCs' osteogenic differentiation. This research highlights the potential of apigenin in promoting bone formation by counteracting the negative impact of inflammation on MSCs, offering insights into novel therapeutic strategies for bone health and regeneration. In continuation of our previous study, we used the 6-prenylatedapigenin, the positive results of which will be published. So, these natural agents may help restore the balance between bone formation and resorption, making them potential therapeutic candidates for inflammatory bone diseases. In summary, inflammation significantly impairs the osteogenic potential of MSCs through various molecular mechanisms. Natural compounds with anti-inflammatory and pro-osteogenic properties may offer a promising approach to counteract the detrimental effects of inflammation on bone health and regeneration
